Application led January 12,1929@ Serial No. 612,193.

To all whom t may concern.'

Be it known that I, EMMANUEL LAVALLEE, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Shuttles; and I do'jhereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and yuse the same.

The present' invention relates to an improvement in shuttles.

In many mills today there are in use both 'plain and automatic looms, and it is obviously a matter of economy that bobbins adapted for use in the automa-tic looms should sometimes be used in plain looms,

so that bobbins as theyv come along may be used either in the plain orautomatic looms as occasion of convenience demands. The ordinary plain loom is provided with a dif ferent .shuttle from that employed in the automatic looms and one not ordinarily adapted fora use in holding bobbins adapted for use in the automatic looms..

The object of the present invention is to produce a shuttle for use in plain looms having features of construction adapting it for convenient use with bobbins ordinarily used in shuttles of automatic looms. To this end the present invention consists in the shuttle for plain looms hereinafter described and particularly defined in the claims.

In the accompanying drawings illustrating the preferred form of the invention, Fig.'

/1 is a plan of the shuttle; Fig. 2 is a section i taken on the line 2 2, Fig. 1; and Fig. 3

is a longitudinal section of the right-hand end of the shuttle shown in Fig. 1.

The illustrated embodiment of the invention is described as follows: The shuttle 10 is provided with an eye 12 of any usual or convenient form used for plain looms. 'Ihe bobbin holder consists of a spring 14 havlng the -usual jaws provided with grooves -16 for receiving the rings 18 of the bobbm 20. The bobbin holder is provided with a gulde 22 of the usual form except that it is slotted at its front end to receive the bobbin pin 24 A vpivoted at 26 on the bolt 28. The bobbin pin 24' is recessed at 30 so thatwhen it is swung upwardly, as shown 1n broken hnes notch. The guide 22-fis secured to the shuttle by the screw 34 in the usual manner.

The bottom plate 36 of the guide 22 extendsv under the bobbin spring 14, and the plate 32 rests upon its upper surface, such bottom -p'late and plate 32 bein received in grooves in the shuttle and held 1n place by thescrew 34 and the bolt 28.

In operation the bobbin pin 24 is raised` to the position shown in broken lines in Fig. 3, the bobbin is thrust on it, and then pressed downward,the bobbin acting4 as an extenslon of the lever of the bobbin pin, aifording a convenient lever means for forcing the bobbin butt between the jaws of the bobbin spring, where it will be held in place by the spring. The bobbin will be thrust down on the bobbin pin until the end 0f the bobbin strikes the guide, and then as the pressure is exerted upon the bobbin, it will be pushed outwardly on the bobbin pin by the slide, and will enter the space between the jaws of the bobbin spring.

The two sides of the guide not only affordguiding means to guide the bobbin -down into the shuttle, but they also servel consists .in the present shuttle merely of a f device for assisting the operative to insert the bobbin in the'shuttle. The bobbins, it will be observed, are as well adapted for use "in automatic looms as in plain looms, and inasmuch as hobbins are much more numerous than the shuttles, itis a convenience and economy to adapt the shuttle of the plain loom to receive the bobbin of the automatic, rather than to use a special bobbin for the plain looms. In other words, ordinarily both the bobbins Aand the shuttles are required to be especially adapted for the plain looms, andthe present invention eliminates the necessity of adaptingboth to this loom, as the shuttle alone 1s made special.

Having thus described the invention, what is claimed is:

1. A shuttle for plain looms vhaving an eye and a bobbin holder, the latter comprising a stationary double jawed bobbin spring of the Northrop loom type and a pivoted bobbin pin, and a bolt for holding the shuttle spring in lace in the shuttle 5 and constituting the plvot for the bobbin 2. A shuttle for plain looms having an eye and a bobbin holder comprising a bobbin spring provided With two bobbin holding arms, a butt guide provided with a medial groove, a bobbin pin received in the groove in the guide, and a bolt for securing the bobbin spring and bobbin pin in place.
